8、 SYSTEMS FOR ELECTRICAL INSTALLATIONS Part 2-3: Particular requirements Slotted cable trunking systems intended for installation in cabinets FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical commit

9、tees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical

10、Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental a

11、nd non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreeme

12、nts of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and

13、 are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote i

14、nternational uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated

15、in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All

16、users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or

17、other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publicatio

18、n. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such pa

19、tent rights. International Standard IEC 61084-2-3 has been prepared by subcommittee 23A: Cable management systems, of IEC technical committee 23: Electrical accessories.

25、IEC 2017 5 CABLE TRUNKING SYSTEMS AND CABLE DUCTING SYSTEMS FOR ELECTRICAL INSTALLATIONS Part 2-3: Particular requirements Slotted cable trunking systems intended for installation in cabinets 1 Scope This part of the IEC 61084 series specifies requirements and tests for cable trunking systems (CTS)

26、and cable ducting systems (CDS) intended for the accommodation, and where necessary for the electrically protective separation, of insulated conductors, cables and possibly other electrical equipment in electrical and/or communication systems installations. The maximum voltage of these installations

27、 is 1 000 V AC and 1 500 V DC. Slotted cable trunking systems are intended for mounting inside cabinets in electrical and/or communication system installations. This document does not apply to conduit systems, cable tray systems, cable ladder systems, power track systems or equipment covered by othe

45、ength having a length of (250 5) mm. Before the test non-metallic and composite slotted trunking lengths are aged at the temperature declared according to Table 3 of Part 1 with a tolerance of 2C for (168 4) h continuously. BS IEC 61084-2-3:2017IEC 61084-2-3:2017 IEC 2017 9 The sample is securely fi

46、xed, using 10 mm external diameter flat metallic washers and appropriate metallic screws to a rigid smooth support such as a plywood board 16 mm thick. When 10 mm external diameter is too large, suitable smaller washer and appropriate screw are used. Fixing(s) are positioned as shown in Figure 103 a

47、t (200 5) mm centres along the length of the sample. Within the width of the sample: for trunking with a width less than 50 mm, one fixing is used as shown in Figure 103 a); for trunking with a width equal or greater than 50 mm, two fixings are used as shown in Figure 103 b). If the manufacturers in

48、structions require the use of cable retainers or dividers, these are fitted according to the manufacturers instructions. Cable retainers, if any, are symmetrically fixed along the length. The sample is subjected to an evenly distributed load of 0,8 g/mm2of the declared usable area for cables, per me

49、tre length. The load is distributed between the compartments proportionally to the declared usable area. The load consists of copper insulated conductors or cables complying with class 5, Table 3 of IEC 60228:2004, or flexible insulated conductors or cables of similar mass per meter. To allow for settlement of the sample, a pre-load of 10 % of the load is applied and removed after (300 30) s. The measurement apparatus is then calibrated to zero. In
